plenty of them here, and we could take them home if we 
knew on what they feed. Do the females lay their eggs on 
any plant, or in the ground; and what is that plant? They 
appear very feeble if kept for a night in confinement, but 
recover and shine when placed out on the dewy grass.—

[I have often tried to establish a colony of glow-worms, 
but have always failed: the light becomes more feeble, night 
after night, until it dwindles to a spark and disappears. The 
eggs are attached by means of a kind of liquid glue to a 
variety of substances, as moss, grass, dead wood, or even 
earth, apparently without any especial reference to the food of 
the larva, except that they are generally found in places 
where its food occurs, as damp ditches and shaded hedge- 
banks: that food consists of the eggs and young individuals 
of different species of land-snails; Zonites cellarius and 
Z. alliarius are especial favourites. The larve attain their - 
full size in April, and then turn into quiescent pupe, but 
still retain great muscular power, as evinced by their writhings 
and twistings when teazed or otherwise annoyed: the pupa 
can also move its head, antennz, and legs; the female pupa, 
as in the perfect insect, exhibits no trace of wings or elytra; 
the male pupa, on the contrary, has the usual representatives 
of these organs. The universally received hypothesis that the 
light of the female glow-worm—like a chignon, a pannier, or 
a crinoline, among ourselves—is a lure to attract the male, 
requires investigation and consideration. I cannot disprove 
it; but the presence of this luminosity in.the egg, larva and 
pupa, and also abundantly in the males of some allied 
species, seems to point to the desirability of some other 
explanation.— Edward Newman.] 
Bees Fertilizing Flowers.—I shall be very grateful to any 
reader who will procure and send me the bees which frequent 
the bloom of the scarlet-runner or the red clover. It is well 
known to those who have studied the subject that these 
plants cannot fertilize themselves, but are dependent on 
insects for the performance of that office. Our countrymen 
resident in Central America, where the scarlet-runner would 
be a most acceptable vegetable, cannot cultivate it to any 
good purpose, because the natural fertilizer is not indi- 
genous, and has not been introduced. In like manner the
